Based on said structure and setting, the sewage-treatment plant course of work of the present invention is as follows:

Referring to Figure 11, in filter process, close the first switch valve 101, the 3rd switch valve 103, open second switch valve 102, the four switch valves 104; Gas explosion air pump drives the gas explosion hole 461 on aerating pipe 46 to carry out gas explosion.Water purifying tank water pump 31 passes through in collecting pipe 6 and the interior manufacture vacuum of water purification header 5, and coordinate the suction of cesspool water pump 30, make sewage in cesspool 20 via sewage inlet 44 suction basic filtering modules 200, due to the existence of inside and outside differential pressure, water body permeates to through hole 22 by the substrate of ceramic filter plate 2, this process filters the sewage from cesspool 20, ceramic filter plate 2 can also carry out adsorption filtration to the organic matter in heavy metal ion and water body in filter process, therefore, water purification after filtration is also equivalent to be sterilized, the water purification of a plurality of through holes 22 collects and via pure water inlet 12 in the water purification cavity volume 131 of end connecting plate 13, water purification header 5 flows into collecting pipe 6 and carries out centralized recovery by water purifying tank 40, thereby completed dirty water purification.In above process, because aerating pipe 46 does not stop gas explosion in sewage cavity volume, can make on the one hand the organic matter in sewage fully be oxidized expansion and be unlikely to stop up ceramic filter plate 2, the vibration that gas explosion process produces on the other hand can be rinsed the dirt on ceramic filter plate 2 surfaces, further improves filter efficiency.

Referring to Figure 12, after use after a while, first close the first switch valve 101 and the 3rd switch valve 103, open

second switch valve

102,32 work of instruction recoil air pump, compressed air overflows from ceramic filter intralamellar part by recoil, thereby complete for the first time, rinses; Secondly, open switch valve 103, by water purifying tank water pump 31, from back-flushing entrance 43 and pure water inlet 12 places of upper end cover 41, to the interior injection water purification of basic filtering module 100, ceramic filter plate 2 is carried out to air water back washing, complete for the second time and rinse, in this process, water purification from pure water inlet 12 places is gone forward side by side into basic filtering module 100 from ceramic filter plate 2 inside to exosmosis, and impurity such as silt, organic matter that is attached to ceramic filter plate 2 surfaces etc. is rinsed and peels off; Phase III; Close the second valve 102, the 3rd valve 103 and the 4th valve 104, open the

first valve

101,30 work of instruction cesspool water pump, sewage directly rinses by 45 pairs of filter 12 surfaces of the jet pipe in back-flushing entrance 43 and upper end cover, this process is also the process to the water filling of sewage cavity volume simultaneously, and when the water level of sewage cavity volume approaches upper end cover 41, ceramic filter module restarts the filtration of next circulation.

Should be appreciated that; the disclosed content of above embodiment is only the part preferred version of the claimed technical scheme of the present invention; those skilled in the art do not depart from the spirit and scope of the present invention can also carry out various changes or modification to above-described embodiment; if these are changed and within modification belongs to claim of the present invention and equivalent technologies scope, the present invention also means and comprises these changes and modification.
